COMPONENT
CHECKOUT PROCEDURE
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
HIGH-VOLTAGE
CAPACITOR
Including
bleeder
resistor
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
HIGH-VOLTAGE
DIODE
Measure the resistance: Across two terminals with
an ohm-meter on highest scale.
FUSE DIODE
RESULT
Normal reading:
Momentarily indicates several ohms,
and gradually to 10 meg-ohms.
Abnormal reading:
Indicates continuity or 10 meg-ohms
from the beginning.
Normal reading:
Indicate about the middle position in one
direct (forward) and infinite ohms in the
reverse direction, using meter with a 9-
volt battery.
- Some digital meter may show over even
in a forward direction because low mea-
suring voltage of meter does not allow
the meter to pass through the high volt-
age diode.
Abnormal reading:
Indicates continuity or infinite ohms in
both directions.
Normal reading:
Indicate infinite ohms in both directions.
Abnormal reading:
Indicates continuity in both directions or
continuity in one direction and infinite ohms
in reversed direction.
